Characteristics of Life
Characteristics of Life
This characteristic of life means living things must take in and use energy.
What is metabolism?
This scientist looked at cork cells and gave us the word “cell.”
Who is Robert Hooke?
If you want to view a living paramecium swimming in pond water, which microscope would you use?
What is the Light microscope?
Which type of cell has no nucleus?
What is a Prokaryote?
Which part of cell theory explains why cutting your finger heals over time?
What is All cells come from pre-existing cells?
A sunflower bending toward sunlight is an example of which characteristic of life?
What is response to stimuli?
This scientist improved microscopes and was first to see living single-celled organisms.
Who is Anton van Leeuwenhoek?
Which type of microscope gives the highest magnification and detail, but cannot view living specimens?
What is the Electron microscope?
Bacteria are an example of which type of cell?
What are prokaryotic cells?
Which three structures are found in plant cells but NOT in animal cells?
What are cell wall, chloroplasts, large central vacuole?
Explain the difference between something dead and non-living.
Dead was once alive, non-living never showed characteristics of life.
This scientist stated that all cells come from pre-existing cells.
Who is Rudolf Virchow?
If an eyepiece lens is 10x and the objective lens is 40x, what is the total magnification?
What is 400x?
You look under a microscope and see that the specimen you are looking at has a cell wall and chloroplast. Is it prokaryotic or eukaryotic? If eukaryotic, a plant or animal cell?
What is Eukaryotic and Plant cell?
Name the three parts of cell theory.
What is All living things are made of cells / Cells are the basic unit of life / All cells come from pre-existing cells?
An oak tree produces acorns every fall. Which characteristic of life is this?
What is reproduction?
These two scientists concluded plants and animals are made of cells.
Who are Schleiden and Schwann?
A scientist wants to study the 3D surface of a beetle’s exoskeleton. Which microscope should they choose?
What is a Scanning electron microscope (SEM)?
A eukaryotic cell is about 10–100 µm, while a prokaryotic cell is about 1–10 µm. How many times larger can a eukaryotic cell be compared to a prokaryotic cell?
What is up to 100x larger?
If a cell is compared to a school, the cell membrane could be like what part of the school?
What are the doors or security system (controls what enters and exits)?
A single-celled organism moves toward a light source, grows larger, reproduces, and maintains internal balance despite changing water conditions. Identify all the characteristics of life shown in this scenario.
What are Metabolism, growth and development, reproduction, response to stimuli, homeostasis?
Put these scientists in correct order of their discoveries: Hooke, Virchow, Schleiden, Leeuwenhoek, Schwann.
Hooke (1665) , Leeuwenhoek (1670s) , Schleiden (1838), Schwann (1839), Virchow (1855)
Explain why magnification of a specimen is not always as important as resolution of an image?
What is Magnification makes an object look bigger, but resolution determines how clear and detailed the image is. Without good resolution, increasing magnification just makes a blurry image larger.
A cell has ribosomes, a cell wall, DNA floating in the cytoplasm, but no nucleus. Which type of cell is it?
What is a Prokaryote?
Why is cell theory considered important in science? Give two reasons.
What is It applies to all living things / helps explain growth & repair / forms the foundation of biology?
